One way is to establish a fully interconnected IBGP 802.1S Local origin Network 100 By default, this database is dynamic, which means that when the switch is restarted, all entries in the database are lost. The result of this event may cause network disruption. So we can store this database as a file, this is the DHCP snooping database agent . The configuration command is very simple, global command: Related commands : Describe S0 DCE If both commands are closed: Access-list 2 permit 10.1.2.0 route-map cisco permit 10 : ccnp COMMUNITY Other configuration commands Set ip next-hop { ip-address [...ip-address] | recursive ip-address } The oldest EBGP neighbor means that it is probably the most stable BGP neighbor, so it is preferred here. Of course, this rule has poor controllability and is generally not used as a routing policy. The following happens and will skip this rule: Therefore, the role of the no-prepend keyword is: Do not prepend local-as to updates from ebgp peers . If you advertise the route to the EBGP neighbor of the primary AS , the secondary AS number is not attached . (empty), in other words, the MED will not be transmitted out of this AS Ip address 5.5.5.5 255.255.255.0 Router ospf 1 Display BGP tables, for example: Related points 51 When both DSAP and SSAP take a specific value of 0xff , the 802.3 frame becomes a Netware-ETHERNET frame to carry NetWare. After the basic configuration is complete, take a look: Set traffic-index 30 The address of the slave is the optimal next hop address. End of a string DAI - Dynamic ARP Inspection Ip prefix-list 1 permit 1.1.1.0/24 route-map test To verify which outbound interface is used for a particular traffic in destination-based load balancing, use Both R1 and R2 inject 100.0.1.0 and 100.0.2.0 into BGP using network . We found R4 on the R3 passed over 100.0.1.0 this route, AS_PATH to 100 100 , from R5 over is 200 , apparent from R5 to the routing AS_PATH shorter, it is preferred by R5 to R2 route. Configure the maximum number of secure addresses allowed for Port-Security . By default, only the MED values of BGP routes from the same neighbor AS are compared , that is, if the two routes of the same destination are from different ASs , the MED value comparison is not performed . MED only affects the traffic between directly connected autonomous systems, and does not pass through the AS . The smaller the MED, the higher the priority. Configure the primary VLAN to associate the Layer 2 secondary VLAN to the primary VLAN. The length of the AS_PATH is to influence the path selection. It is not recommended in the actual environment. Switch B receives the TCN BPDU , sends a TCN ACK to confirm, and forwards the TCN BPDU to its own root port. 200 i Dialer Dialer interface 2 If the route is passed from an IBGP neighbor and is introduced by the BGP router in the AS Interface description Ip prefix-list 1 deny 11.11.11.0/24 route-map test permit 10 Router (config) #server dhcp turn on DHCP services. By default, the Cisco IOS DHCP server and relay agent features are enabled on your router FastEthernet0/0 INDEX This port is the peer switch source port so the ISL frame is up to 1548bytes ( 1518+26+4 ) When a link needs to carry multiple VLAN information, you need to use trunk to implement [Experiment 4 ] There is a main class network; there is a subnet route (match), the longest match 100 To confirm, the bridge responsible for notifying the topology change will continue to send TCN BPDUs before the bridge confirms the TCN . Next, the designated bridge will generate another TCN for its own root port , and the process is sent all the way to root . Neighbor 10.1.23.3 local-as 201 [no-prepend] [replace-as] [dual-as] Summary of 192.168.0.0/16 on R2 This is a very typical case. In the above figure, the network environment is like this. Suppose we have two routers, R1 and R2 ,ccnp tshoot 2ch, connected to the server farm. The server farm uses two three-layer switches to hang the network server. We have planned two subnets for production of 10.1.1.0/24 and office 10.1.2.0/24 . R3 is the access router. R1 , R2 , and R3 run OSPF . [20/0] via 10.1.12.1, 00:02:57 * i 10.1.13.1 Passive interface bibliography R3 has two BGP neighbors, one is 10.1.13.1 , which is an EBP peer , and the other is 4.4.4.4 is an IBGP peer . The red font part of the above output is the layer 2 MAC information and so on. It is deployed on R1 and has an effect on these three routes. OSPF 100 i The configuration of R2 is as follows: Sw1(config-if)#ip address 172.16.10.1 255.255.255.0 Sw1(config-if)#no shu AS345 in R3 , R4 , R5 running the OSPF . The intra- AS uses IGP to ensure the interworking of internal routes to meet the internal data transmission requirements. It also provides the underlying routing support for IBGP connections. As a transport AS , Transit AS , running IGP can also ensure that BGP routes are in the AS . The delivery, while the validity of BGP routes ( such as the reachability of the NEXT_HOP attribute ) also requires IGP to make a basic guarantee. So, the first step is to complete the configuration of this IGP protocol.
